If your focus is on being in a key location in BA and you don't need the frills of the better hotels, this will suit you nicely. It's a little dated with fairly antiquated lifts etc, but everything works and is clean. Breakfast was fine and the room was quiet.
Our only issue was that it took an hour to get a taxi but not really the hotels worry.

We stayed here as part of a tour, so stayed two separate nights, in different rooms, two weeks apart. Location is fantastic, being only a block from Place de Mayo and several metro stations.
Our first room had a broken light switch with exposed wires, threadbare towels and a musty smell.
The bathroom of the second room had ants around the sink (I squashed more than 15, although I couldn’t tell where they were coming from) and also had a broken light switch but wasn't dangerously so.
Breakfast was adequate and all rooms have safes. The wifi was free but not strong and kept dropping out
I would suggest that if you have a choice then book somewhere else - there are better places.

I visited Buenos Aires due to some family commitments, and needed a small hotel located in a central area of town. This lovely hotel was just what I was looking for! Located half a block from 2 Subte (Underground Metro) Stations, a few steps away from a main Avenue, Pharmacies, Cafes, Restaurants, Minimarkets and a convenient Shopping Street.
The Hotel Staff was kind, helpful and very pleasant anytime they were approached for any queries or information of any kind. My room was small but neat and the bed was comfortable. The bathroom was clean and even had a small bathtub. It seemed to me that there were larger rooms available as well, in case the number of travellers was higher.
The continental breakfast was simple, fresh and tasty, and the staff were lovely and polite.
Overall a reasonably priced, lovely little hotel for a convenient stay. Thank you to the whole team!
